GIL BURNER.

' ed for heating or cooking, and the object of my improvement isto provide a burner that shall be simple in its construction, easily cleaned, reliable and efficient in its operation and that shall be adapted to utilize for its fuel different mineral oil products or gases, and a further object of my invention is to provide a burner that readily may be attached to different kinds of stoves that are already in general use.

I attain these objects by devices illustrated in the accompanying drawings wherein- Figure 1 illustrates a burner embodying my invention by a View in front elevation in which broken lines. indicate the form of some internal parts fragments of a stove with which it is associated being indicated by a view in vertical-section, Fig. 2 is av view of the same in side elevation, Fig. 3 is a plan View of the same with a small portion broken away to permit more space; for

the drawing of Fig. 1, Fig. 4 is a fragmentary view in horizontal section on broken line w-m of Fig. 2, Fig. 5 is a view of a structure embodying my invention in side elevation wherein some of its parts are of a modified form, Figs, 6 is a view in front elevation of my invention showing another modified form of some of its parts and Fig. 'Zis a view in horizontal section on broken line y-y of Fig. 2.

Like reference numerals indicate like parts throughout the drawings.

- Referring to Fig. 1 of the drawings, 9 is the body of a burner, preferably of castiron, of cylindrical shape whose bottom end is convex in form and whose top end is flat. Extending downwardly from the top of the body 9 and concentrically with its external circumference is a passageway 10 leading into an opening 11 which extends fromrone side of'a lower portion of the body 9 and through to the other side thereof whereby Specification of Letters Patent.

oppositely disposed segments 12 are left to unite the lower portion of the body 9 with the upper portion thereofthus foyming a passageway between the top of he said body 9 and oppositely disposed openings 11 extending through the lower portion of said body 9. With-in the lower and convex portion of the body 9 is a chamber 13, whose outline is indicated by broken lines, into the bottom of which chamber 13 leads a fuel feed-pipe 14, indicated by dotted lines, to whose lower end is connected a T 15 which is provided on its lower end with a nipple 16 and a valve 17 to which is connected :1 drain-pipe 18 while to the slde opening of said T 15 is connected a nipple 19 connecting witha valve '20 which may control the i flow of fluid fuel that may be conducted through pipe 21 which may lead to a source of supply not shown. Thus when it is desired to drain out the dirty sediment thatmay accumulate in the bottom of the chamber 13 one may close the valve 20 then open' the valve 17 to permit the dirty oil to drain out of said chamber 13. Extending upwardly from the chamber 13 through one of the segmental portions 12, and indicated by broken lines 22 is a passageway which,

at apoint near the upper end of such segmental portion 12, divides into two spiral passageways indicated by dotted lines 23,

one of which extends upwardly and spirally in one direction Within, and to the top of, the body 9- to connect with an outlet pipe 2 1 while the other spiral passageway 23 turns upwardly and spirally in the opposite direction to connectwith the same outlet pipe 24, as indicated'by dotted lines in Figs. 2 and 4. This outlet pipe 24 is bent towardthe center of the body 9 and thence downwardly to terminate in a burner tip 34 just above the top line of the body. 9 whereby fluid fuel may be projected downwardly to the bottom of theopening 11 to flow out of such openings 11 to drip thence into a priming pan 25 in the operation of lighting the burner. The priming pan 25 is d1sposed beneath the body 9, the fuel feed pipe 14 passing through a hub in the central portion of its bottom as indicated by broken lines. Two projecting bosses 26,'dispose.d on opposite sides of the convex bottom of the body 9, are drilled and .tapped to form'holes leading into a chamber 13' which holes may be plugged under some conditions of operations or under other conditions one or both of these may be connected with a pipe 27 which may lead to a source of steam or coinpressed air" or to a source of liquid fuel supply, not shown, as conditions may re quire.

The priming pan 25 is disposed to rest on a supporting plate 28 thus to support the body 9 of the burner through the medium of the feed-pipe 1 1- to which the hub of the priming pan 25 is fastened. The plate 28 is adapted to rest on a sheet 29 of non-combos tible material, as asbestos, which sheet 29 may rest upon and cover a grating 30 of the fire-box of a stove, the sheet 29 thus disposed serving to prevent air from passing directly from the space beneath the grate in a stove to the space above such grate but such sheet 29 is provided with holes 31 which register with the mouth of air-pipes 32 Whichexte'nd through the plate 28 at oppositely disposed points, upwardly to and over the top of the body 9 to turn downwardly to permit the flow of air directly into the passageway 10 through which such air may reach the openings 11, while the mouth of two other air-pipes 33 register with like holes 31 to extend upwardly through plate 28 to deliver air into the opening 11 on each side of the burner body 9. Thus in the operation of the structure of Figs. 123- 4 and 7 the valve 17 is closed and the valve 20 is opened slightly to let oil flow upwardly through pipe 14 to fill the chamber 13 thence to rise in the passageway 22 through one of the segmental portions 12 of the body 9, thence o divide to flow in two streams in opposite directions through the two spiral passageways 23 which streams then unite at the top of theburner to flow through pipe 2 1 to the tip 34 from which tip 3 1 it is emitted to fall through the passageway 10 to the bottom of the opening 11 to drizzle over the sides of the lower portion of the body 9 into the priming pan 25 and when suflicient fuel has been received by the priming pan 25 then the valve 20 is closed and the fuel within the priming pan 25 then lighted to burn to heat the body of the burner 9 to such temperature as may volatilize or gasify the fuel flowing through thetortuous passageways 23 thus to cause gas instead of liquid to be emitted from the burner tip 34 and when the body 9 reaches such temperature the valve 20 may be opened just suiticiently to permit a constant rate of flow of fuel to produce a desired volume of flame. and under such conditions the holes through the bosses 26 would be plugged by a suitable screw-plug butfor some purposes one or both of such plugs might be replaced by a pipe 27 leading from a source of steam or compressed air, the passageway in such pipe 27 being controlled by a suitable valve, not shown, and thus such steam or air might be caused to mix with the fuel admitted by the pipe 14 more rapidly to volatilize such fuel and cause it to be in the form of gas when emitted from the burner tip 31. The tortuous passageways 23 perform the important function of subjecting the fuel to the heat imparted to it by the burner body 9 during its flow for the long distance around the inside of the body 9 thus to give such fuel time to heat and volatilize before'reaeh-. ing the point of combustion.

In Fig. 5 I have shown some parts of the structure of Fig. 1 in connection with a modified form of air-pipes comprising two air-pipes 35 extending upwardly from holes 31 in the sheet 29 parallel with the body 9 to and over the top of body 9 and to the top of the passageway 10 that extends downwardly in the body 9. At points opposite the openings 11 branch outlet pipes 36 are provided to conduct and direct air into said openings 11, such outlet pipes 36 serving to take the place of the air-pipe 33 of the structure of Fig. 1. In other respects the structure of Fig. 5 is like the structure of Fig. 1 in construction and mode of operation.

In Fig. 6 I have illustrated another form of air-pipes 37 that maybe substituted for the air-pipes 32 of Fig. 1. The air-pipes 37 extend spirally upward each half way around the body 9 from the holes 31in sheet 29 to and over the body 9 to the central passageway in body 9 that extends downwardly to the openings 11. By thus forming the air-pipes 37 the air flowing therethroughv may pass for a longer distance within the space heated by the burner to heat such air to a higher degree of temperature before it reaches the point of combustion.

A structure embodying my invention, as described, may be placed within the fire-box of astove to rest upon the grate thereof, and the usual devices for controlling the admis sion of air into the space beneath such grate may be employed and the usual type of stove-pipe may be employed for carrying off the products of combustion from the space above such grate.

1. In a fluid fuel burner of the class de- .scribed, a burner body, preferably of castiron, provided with a fuel chamber in its lower portion, a transverse opening extending through said body at a point above and adjacent to said chamber, a central flue extending upwardly from said transverse scribed, a burner body provided with a fuel chamber, a transverse opening extending through said body adjacent to and above said chamber, a central flue extending from the top of said body downwardly into said transverse opening, means for feeding fuel and compressed fluid into said chamber, spiral passageways within the wall of said body extendlng from said chamber to and out of the top of said body, a burner tip disposed to emit fuel downwardly into said central flue, a pipe connecting said tip with the top of the said spiral passageways, and. air

flues extending spirally upward from a point adjacent to the base of said body to s my name this twenty-seventh day of Sep- 20 telnber, A. D. 1912.
